Many Yuanying powerhouses have already seen the approximate size of this wave of demon clan vanguard troops through their powerful divine senses, the number is at least two million or more, and there are as many as fifteen beast kings above the seventh order who are leading the army.

At the head of the city, the rune arrays have been activated, shining brightly, and they can fire powerful rune cannons at any time.

With the order of a sword boat, the roar suddenly rang out, and a rune cannonball flew out with a "whoosh", drawing a graceful arc in the air and smashing down into the group of demon beasts.

A flying demon beast appeared in the sky, and with a piercing chirp, it quickly rushed towards the human monks at the head of the city.

Scaly Eagles, Goldfinch Owls, Dementor Vultures, Icewing Sparrows...... These most notorious air overlords in the Southern Regions were all dispatched in the first round of attacks from the Demon Clan, aiming to destroy the defenses of the human monk city in one fell swoop.

The rune cannon was very ineffective against flying mobile targets, and soon these flying monsters approached the air area about ten miles away from the city.

At this distance, only some strong people in the Dan Stage can attack each other, and the human cultivators in the Foundation Building Stage and Qi Cultivation Stage are not able to catch it.

The Giant Scale Eagle is currently opening the way, and with its strong scale armor body, it has blocked the magic attack of the Jiedan monk at the head of the city, and protected the demon bird responsible for the attack behind him. The lowest cultivation of these giant scale eagles is also a third-order demon beast, and there are not a few powerful existences of the fifth and sixth orders. With the strength of his innate physical body, even if he was only a third-order giant scale eagle, he could barely block the long-range magic skills of the human cultivators in the early stage of the Yudan.

The Golden-winged Owl and the Soul Vulture, under the protection of the Giant Scale Eagle, unleashed a sonic attack directly at the human monks at the city's head. Even though the distance was quite far, there were still a large number of human monks who bled and fell to the ground, and some even fell directly from the city tower.

"Everyone immediately cast a spiritual power shield to resist the sonic attack of the demon birds. Monk Jiedan will follow me into the air to meet the enemy!" Xin Qianyue's figure suddenly flew off the ground, leading the Jiedan monk of Haofeng Academy to rush towards the golden-winged owl and the group of dementors under the protection of the giant scale eagle.

The monks of the major sects also flew out of the city one after another, and rushed towards the enemy in the air with Xin Qianyue and the others. Only by breaking through the Giant Scale Eagle's defenses can everyone inflict damage on the Goldenfinch Owl and the Dementor Vulture.

So far, the existence of both Yuan Infant levels has all maintained restraint and has not easily joined the battle. As far as the demon clan side is concerned, this is just a tentative attack launched by them, and it is not enough to fight the beast king above the seventh order for a decisive battle as soon as they come up. For the Terran monks defending the city, dispatching the Yuanying-level powerhouses to fight is the last helpless move, which will inevitably bring huge casualties to the warring sides, and the situation will be completely out of control at that time.

After the Terran Monk Jiedan took to the air to participate in the battle, the bulky Giant Scale Eagle could not defend itself against the elusive opponent at all, and the Golden-winged Owl and the Dementor Vulture behind him were suddenly exposed to everyone's attack.

The advantage of being close no longer belongs to these demon birds, but in an instant, a large number of golden-winged owls and soul vultures were killed or severely damaged and fell from the sky.

The human monks at the head of the city rejoiced one by one, and even more vigorously manipulated the city defense equipment to launch a fierce sniper attack on the ground army of the demon clan that was charging all over the mountains and fields in the distance.

The accumulation of rune cannons caused considerable damage to the army of monsters that were charging intensively, and there were constantly monsters that were shattered into the air under the impact of the explosion of the rune cannons.

The one who commanded the attack was one of the fifteen Great Winged Dragon Kings of the Blade Wing Clan, and the Muzun who had cultivated in the early stage of the Eighth Order. He ranked second in strength among the Bladed Dragon King, second only to Qiu Xuan, who had previously threatened the Immortal Dust with Xiang Kuan's Yuan Ying in the Spirit Rhino Divine Palace.

The battle situation in the air and on the ground was very unfavorable to the demon clan's side, which made Mu Zun, who was eager to make meritorious contributions, very unhappy. Of course, he knew that the top powerhouses on both sides were not suitable to strike at this time, but he had to reverse the decline of his side, otherwise he would not be able to explain to the Blade Tyrant Gondor.

Soon Mu Zun let out a series of long roars that rushed straight into the sky, and in the rear of the demon army, a large group of huge winged dragons suddenly flew out, and flew towards the Terran Jiedan monk who was fighting fiercely with the demon birds in the air.

As the dominant race of this beast tide, the status of the Blade Clan is extremely high, and they will not easily participate in such a high-casualty action that charges to open the way. However, in order to open up the current passive situation, Mu Zun could only send the elite forces of the descendants of the Blade Wing Clan.

It must be said that the Blade Wing clan has indeed benefited greatly in the Water Mirror Lost Valley. Originally, there were only eight Bladed Dragon Kings who entered the secret realm with Gondor, and none of them had entered the seventh-order realm. Later, because Gondor was lucky enough to find several important treasures, the strength of the entire Blade Wing clan developed exponentially. Not only did the eight Blade Wing Dragon Kings all break through to the seventh-order realm, but there were also seven existences that were originally only quasi-dragon kings and entered the cultivation of the seventh-order beast kings.

The other Blade Wing Dragons also had a huge advance in terms of cultivation, and there were more than 3,000 people who had entered the fifth and sixth order realms. This is equivalent to the fact that the Blade Wing clan alone has thousands of Jiedan powerhouses, and this number alone is almost on a par with the Jiedan monks of the Southern Regions Sect Alliance Army assembled in Tiandu City.

What Mu Zun sent now was the more than 1,000 fifth- and sixth-order Bladed Winged Dragons he brought this time. Once a powerful existence of this order of magnitude joined the battle, it would be an absolutely devastating blow to the Terran monks.

The speed of the Blade Wing Dragon was extremely fast, from receiving the attack order from the Muzun to launching the charge, it only took a few breaths to reach the airspace where the Terran Jiedan Monk and the Golden-winged Owl, the Giant Scale Eagle, and the Dementor Vulture were fiercely fighting.

At this time, because of the addition of the Ice Wing Sparrow, the advantage of the human Yudan Monk was not as great as before. Although the number of Goldwinged Owls and Dementor Vultures killed was extremely high, there were also many Monk Yudan who were frozen into ice sculptures by Icewing Sparrows and then blasted into pieces.

Yijian Zhou, who was sweeping the formation at the head of the city, saw the group of winged dragons suddenly flying in the distance, his face suddenly changed greatly, and he hurriedly immediately ordered: "The second echelon of the Jiedan monk immediately goes into the sky to meet the enemy!"

This time, the monks of the Southern Regions Sect Alliance were divided into three echelons, and the first echelon was the thousands of monks led by Xin Qianyue before, and more than 100 people had been lost at this time. The second echelon was more than a thousand Jiedan monks under the command of Lin Weiren, the great elder of the Ghost Spirit Sect, and they were originally prepared to be used in a decisive battle. But at this moment, the demon clan's side suddenly pressed up more than a thousand high-level bladed dragons, and Yijian Zhou had no choice but to dispatch this force in advance.

Lin Weiren is the cultivation realm of the Great Perfection of the Dan. In the face of the overall situation related to the survival of the Southern Regions Sect, he was also unequivocal, and took the more than 1,000 Jiedan monks behind him and went straight to the fierce winged dragon group.
